New images from inside a pig farm show the fight’s not over – say campaigners.

Sow stalls are almost history but the animal-welfare activist group Save Animals From Exploitation (Safe) says their campaign to improve the miserable lot of pigs on New Zealand farms is far from over.

Last week Safe’s executive director Hans Kriek said newly released video footage and photos from inside a New Zealand farm show that conditions for pigs are still appalling even when farms are sticking to the letter of the law.

The footage filmed covertly by another activist group Farmwatch shows young pigs wading trotter-deep through concrete-floored pens awash with a slurry of faeces and water – with no dry or clean area for them to sit or sleep.

One piglet in the video – a runt that has failed to thrive – repeatedly falls over as if it has some sort of neurological disorder and is bullied by other pigs.
